i dont no where but i heard it from somewhere.. due to the backpressure or something like that.. i dont even no what that is...
if you ran a 3" system, then you'd lose some bottom end torque.....2.5" is plenty big enough for it until you've done tons to it....2.25" would actually be good enough.....it would free it up enough for a top end improvement, without sacrificing the bottom end
